The European standard series EN 15234, Solid biofuels Fuel quality assurance are provided as a general requirements and additional produc

17、t standards. Additional product standards may extend this series over time. EN 15234 consists of the following parts, under the general title Solid biofuels Fuel quality assurance: Part 1: General requirements; Part 2: Wood pellets for non-industrial use; Part 3: Wood briquettes for non-industrial u

18、se; Part 4: Wood chips for non-industrial use; Part 5: Firewood for non-industrial use; Part 6: Non-woody pellets for non-industrial use. Although these product standards may be obtained separately, it should be recognized that they require an understanding of the standards based on and supporting E

NOTE In these product standards, non-industrial use means - use in smaller scale appliances, such as in households, in small commercial and public sector buildings. According to the CEN/CENELEC Internal Re

20、gulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg,

DIN EN 15234-3:2012-04 EN 15234-3:2012 (E) 4 Introduction The overall aim of this European Standard is to guarantee the wood briquette quality through the whole supply ch

22、ain, from the origin to the delivery of the solid biofuel and provide adequate confidence that specified quality requirements are fulfilled. The objective of this European Standard is to serve as a tool to enable the efficient trading of wood briquettes. Thereby: 1) the end-user can find a briquette

23、 that corresponds to its needs; 2) the producer/supplier can produce a briquette with defined and consistent properties and describe the briquette to the customers. Quality assurance measures should establish confidence in the briquette through systems that are simple to operate and do not cause und

24、ue bureaucracy. Wood briquettes are specified according to EN 14961-3, Solid biofuels Fuel specifications and classes Part 3: Wood briquettes for non-industrial use. DIN EN 15234-3:2012-04 EN 15234-3:2012 (E) 5 1 Scope This European Standard defines the procedures to fulfil the quality requirements

25、(quality control) and describes measures to ensure adequate confidence that the wood briquette specification described in EN 14961-3 is fulfilled (quality assurance). This European Standard covers the production and delivery chain, from purchasing of raw materials to point of delivery to the end-use

26、r. This European standard covers only quality assurance for wood briquettes produced from the woody biomasses stated in EN 14961-1:2010, Table 1 and EN 14961-3. 2 Normative references The following referenced documents are indispensable for the application of this document.

30、biform, polyedric or cylindrical units, produced by compressing pulverised biomass NOTE The raw material for wood briquettes is woody biomass in accordance with Table 1 of EN 14961-1:2010. Briquettes are usually manufactured in a die/mould, with total moisture content usually less than 15 % of their

31、 mass on wet basis. 3.2 additive material which improves the quality of the fuel (e.g. combustion properties), reduces emissions or makes production more efficient 3.3 chemical treatment treatment with chemicals other than air, water or heat NOTE Examples of chemical treatment are listed in informat

35、 MWh/t is 3,6 MJ/kg). 1 g/cm3equals 1 kg/dm3. 5 Quality assurance and quality control measures 5.1 General Quality assurance and control aim to provide confidence that a stable quality is continually achieved in accordance with the customer requirements. It means that specified requirements are fulf

36、illed, but it does not necessarily mean a high quality but a steady and continually achieved quality in accordance with the customers requirements. The customer is the next operator in the supply chain. Customer requirements include not only the fuel quality, but also the quality of the companys per

37、formance, such as documentation (product declaration, labelling of packaging, etc.), timing and logistics (to provide biofuels in time and to agreed performances criteria). Fuel quality assurance needs to be applied to the entire supply chain. As the supply chains for solid biofuels in the most case

38、s needs to be kept very simple, the same documents are often used for documentation of quality assurance and quality control measures. NOTE When the customer is a supplier, a retailer or end user, the customer requirements are usually written in sales contracts. Quality control is fundamentally abou

39、t controlling the quality of a product or process to enable the delivery of the product or service within agreed parameters in the most efficient and cost effective way. The consequences of having good quality control will be a cost effective product and process. 1) Designation symbols are used in c

40、ombination with a number to specify property levels (see for example Table 1, EN 14961-4:2011). For designation of chemical properties chemical symbols like S (sulphur), Cl (chlorine), N (nitrogen) are used and the value is added at the end of the symbol. DIN EN 15234-3:2012-04 EN 15234-3:2012 (E) 7

41、 Quality assurance on the other hand, is about reviewing the products and processes, primarily through data provided from the quality control records and using this data. a) to provide confidence that products are produced within the required specification and processes are operated as they should b

42、e, and b) to assure that over a longer term either consistency is being maintained (stability in process results) or that quality improvements are making the intended impact. 5.2 Traceability Wood briquettes for non-industrial use shall be specified with EN 14961-3. The origin and source of solid bi

43、ofuel is specified by Table 1 in EN 14961-1:2010. There are three parts in the supply chain, illustrated in Figure 1. Figure 1 Simplified example of a wood briquette supply chain All operators in the supply chain are responsible for the traceability of the origin and source of the material delivered

44、 by them. The first operator is responsible for the documents being prepared the first time. The documents shall be available and provided on justified request throughout the entire supply chain according to EN 15234-1. 5.3 Production requirements The methodology described below for quality assuranc

45、e and quality control of the production shall be used, but shall be adjusted for the production requirements of the specific wood briquettes production chain in question. There are six consecutive steps that have to be followed by every stakeholder in the supply chain. The steps are described below.

46、 For examples of documentation, see informative Annex A. Step 1: Define fuel requirements for the final product (see 5.4) Step 2: Document the steps in the production and distribution processes (see 5.5, Figures 2 and 3) DIN EN 15234-3:2012-04 EN 15234-3:2012 (E) 8 Step 3: Identify quality influenci

47、ng factors including company performance (see 5.5, Figures 2 and 3) Step 4: Define Critical Control Points for compliance with the fuel specification (see 5.5 Figures 2 and 3) Step 5: Select appropriate measures to assure the quality of the product (see 5.6) Step 6: Establish routines of separate ha

48、ndling of nonconforming raw materials and solid biofuels (see 5.7) The following information will give a general overview about documenting the requirements for the production in a wood briquettes supply chain. 5.4 Fuel requirements for the final product (Step 1) Wood briquettes for non-industrial use are produced according to EN 14961-3.
